Sixteen-year-old Robert lies anaesthetized. A routine operation has just gone wrong.

'What the hell is that?'

'That, Mr Ryan, is the inside of this boy.'

'Christ . . . It looks like some kind of plastic.'

As Robert slowly wakes, he can hear, he can feel, but he can't scream. The operation isn't over. But life, as Robert knows it, is.

Robert goes on the run, terrified and desperate for answers. But what if the answers are too terrifying to face?
